Color management options
The aim of color management is to reproduce colors as accurately as possible on all devices: so that,
when you print an image, you see very similar colors as when you view the same image on your
monitor.
There are two basic approaches to color management for your printer:
●
Application-Managed Colors: in this case your application program must convert the colors of
your image to the color space of your printer and paper type, using the ICC profile embedded in
the image and the ICC profile of your printer and paper type.
●
Printer-Managed Colors: in this case your application program sends your image to the printer
without any color conversion, and the printer converts the colors to its own color space. The
details of this process depend on the graphics language that you are using.
◦
PostScript (PostScript printers): the PostScript interpreter module inside the printer
performs the color conversion using the profiles stored in the printer and any additional
profiles sent with the PostScript job. This kind of color management is done when you are
using the PostScript driver and you specify printer color management or when you send a
PostScript, PDF, TIFF or JPEG file directly to the printer through the Embedded Web
Server. In either case you have to select the profiles to use as default (in case the job
doesn't specify any) and the rendering intent to apply.
◦
Non-PostScript (PCL, RTL, HP-GL/2): the color management is done using a set of stored
color tables. ICC profiles are not used. This method is somewhat less versatile than the
alternatives, but is a little simpler and faster, and can produce good results with standard
HP paper types. This kind of color management is done when you are using a non-
PostScript driver and you specify printer color management, or when you send a PCL, RTL
or HP-GL/2 file directly to the printer through the Embedded Web Server.
NOTE:
There are only two color spaces that the printer can convert to its own color space
using the stored color tables: Adobe RGB and sRGB if you are using Windows, Adobe
RGB and ColorSync if you are using Mac OS.
ColorSync is the Mac OS built-in Color Management System; so, when you select
ColorSync, color management is performed by Mac OS, and it is done based on the ICC
profiles of the specified paper type. ColorSync is available with the PCL3 driver only.
ColorSync can be selected under Mac OS X 10.4 from the Color Options panel: select
Use Embedded (ICC/ColorSync) from the Source Profile drop-down list. Under Mac OS
X 10.5 and 10.6, ColorSync can be selected from the Color Matching panel.
You are recommended to consult the Knowledge Center (see
) to
see how to use the color management options of your particular application.
To choose between Application-Managed Colors and Printer-Managed Colors:
●
In the Windows driver dialog: select the Color tab.
●
In the Mac OS Print dialog: select the Color Options panel.
●
In some applications: you can make this choice in the application.
Printer emulation
If you want to print a particular job and to see approximately the same colors that you would get from
printing the same job on a different HP Designjet printer, you can use the emulation mode provided
by your printer.
